Jace, Oath Keeper

+2: Until your next turn, whenever a creature attacks you or a planeswalker you control, you may draw a card, then discard a card.
-2: The next time you cast an instant or sorcery spell from your hand this turn, put that card into your hand instead of your graveyard as it resolves.
-10: Search your library, hand, and graveyard for up to three instant and/or sorcery cards and exile them. For as long as they remain exiled, you may cast them without paying their mana costs.
Shuffle your library.
